The warning lamp system has a main transformer (10) with its primary (12) supplied by an AC source and its secondary (13) supplying multiple individual lamps units (14-1 to 14-3) connected in series. Each lamp unit is a fluorescent lamp with an individual transformer (18-1 to 18-3), started by the overvoltage produced when its transformer is supplied and the lamp is non-conducting. |
